Re: Generating Victor compatible PWM's

If you mean the control signal, it's the standard hobby servo PWM. 1.5ms is neutral, 2ms is forward, 1ms is reverse. Forward and reverse might be backwards...but 2ms goes full one direction, 1ms goes full the other direction. Anything in between is proportional. You need to send the signal every 20ms or so (this timing isn't critical). Servos go to sleep if they don't get the signal after 30ms, but I'm not sure what happens with the victor. If you send it too often, it gets confused and does weird things.
